ANTP228 Posted March 7, 2008 Report Share Posted March 7, 2008 the reverse light wire is in the rear view mirror harness on the wind shield, you know the mirror that you look at while backing up? that is where it is in the front of the truck, also usually they can be found in the driver side kick panel, in that harness that runs to the rear of the vehicle.
